fix: 合并 main 后的测试回归修复

- index.ts: 移除 #130 遗留的 ctx.on('session/disposed')（fake ctx 无 on，
  且 #130 已按取 HEAD 决策，closeSession 调用方一并移除）
- browser.probe: 405→GET 重试后跳过 embed-signals GET，避免多余第 3 次请求（#69）
- EditorHost: 移植 #228 的 dirty 确认守卫到 HEAD 的 reloadSeq 结构（refreshFile）
- tests: fake ctx 补 get()（#357 ctx.get 回归，free-window/editor-refresh/markdown）
- tests: prefs 期望对象补 browserAllowedLoopback（smoke/plugin-shape/state）
- tests: builtins 浏览器设置行补 browserAllowedLoopback（#69）
- tests: install-powershell BOM 门限仅对实际文档化远程调用的文件生效
- locales: 19 语言补齐 showInFolder / refreshUnsavedConfirm（#94 #215 #228）
